So I'm currently experiencing a problem with my headphones (some parts of the audio aren't coming through), and before sending them in for repair, I thought I'd do a little debugging myself, but it's too hard for me (possibly because I have no experience whatsoever in sound equipment). Is there somewhere on SE I can ask a question about this problem?
It seems to be off-topic on Audio.SE, which is about audio recording and production, not general audio equipment.
Super User, similarly, seems to be a bit of a stretch—although it seems to be where most of the questions about headphones have gone historically, it's not really a computer problem, since the same problem happens when plugged into mobile devices, etc.
Basically, I'd like to know if there's an SE site I'm not aware of, or, if not, if it's actually on topic on Audio or SU.
